Evaluation is a massive problem in RMPS. This is because students can't do it, don't do it or don't know how to do it and if they don't know how to do it, this may be because they just don't get it or, worse still, maybe the teacher isn't clear either. Evaluation is not simply writing down a list of the views of two sides of an argument. It is much more than that and your job when you are evaluating is manipulate your information so that it becomes evaluation. Here's the kind of thing that many students think is evaluation
Religious people believe in God because thay have the cosmological argument. This is the idea that everything that exists has a beginning and since the universe exists it has a beginning. There is no such thing as an infinite chain of causes. There is a First Cause and this cause is God.
People disagree with this argument because there is no proof that the first cause is God. Also the universe might be infinite because there is such a thing as infinity. Also some things we have not discovered yet could have no cause and there may not be an infinite chain of causes.
This isn't evaluation. It is just a descripton of two sides of an argument and therefore would not count as evaluation. This is evaluation:

However, this argument could be criticised on the grounds that whilst the argument might prove that there is First Cause, it still has a lot to do to prove that it is God. It is difficult to see how one can infer an omnipotent, omniscient, good and loving God from the basic argument provided because there is no information in the aergument on that. A further criticism of the argument is its basis which is that an infinite chain is impossible. This is just a presumption made by Aquinas without any justification. It is almost as if he considers it so obvious that there is no need to explain it but there is because it is a fundmental idea of his argument. The argument also suffers from another presumption which weakens it and it is that everything that exists has a cause. The point might be fine philosophically, but in science Alan Guth has shown that it is possible in theory at least for bubbles of energy to pop into existence and out again without cause. There is also inductive thinking going on where based on Aquinas' limited experience of the world he concludes that everything has a cause. He cannot reasonably make that claim unless he has the experience and the data to back it up. He had neither.
Now, I'd be the first to admit that this is a high level answer but hopefully you will be able to see the difference between the two approaches. What I've done is used the views against the cosmological argument and turned them into criticisms rather than just a list of what people say without relating it to the orignal example.
